Agree on all points. Jim Jim, I said earlier “you”and I should have said “we”… Yes, these issues will go through changes and false starts. May need to disable most IRQ lines in the beginning. Yes, and my sheet is going to have issues. I got to thinking later that I did not label the I2C clock as a CLK. Have not gone back to look yet. I like and agree with what Burns said, once we get this all working we probably will not have to touch it any more. Temperature testing will be needed to be sure things work properly. We may also find the pull-up they have on chip is not enough and have to add a pull-up or pull down to the board. I think I have most of them covered but may have missed something. On the lines going to the PC104 I don’t know what is really going to be needed there without a lot more study on the interface. So i just made them inputs mostly to be safe. These lines should all be buffered but I did not want to add the additional chips and current. Careful coordination with others should be the solution but a lot of work there. We can address it later.

This is not to tell you what, but just to get you started looking at HCG. First, the version I am using is 4.07.01, released 11Dec2018. I think this is the latest. It has a few bugs which they never fixed. But in any case, once you start it up, what you want to do is to got to file/Open Project and open the file (from the PacSat software repository) called PacSat.hcg. There is also a PacSat.gil. I've never been sure what that does, and it only occasionally actually changes. These files are in the top-level folder of the repository named "hcg". When this loads, you will see a huge number of tabs. Along the top are mostly the "peripheral" devices like GIO (aka gpio), SCI (aka UART), SPIs, CANs, ADCs, etc When you pick one of those peripherals, say SPI4, you get a second row of tabs relating to the peripheral. In many cases you don't need to change much but post of the peripherals have a "Port" tab which is generally important. On the left column you generally see each logical connection to the peripheral (lets call them pins). For example SOMI (normally called MISO), SIMO (MOSI), CLK, ENA, and a bunch of SCS (chip select) pins. For each one you select whether you want to use it for the peripheral or if you want to use that pin for the peripheral or as a GPIO. Generally if you are using a SPI, you will need SOMI, SIMO, and CLK. I've never quite known what ENA does. But you don't want to use the SCS pins connected to the peripheral. The driver expects them to be GPIO pins for more flexiblity. On the right block, you can see how the pins are set up: Open gate, which direction, pull up or pull down, etc. And finally now the name of the pin (say SPI4 SIMO). Now go back to the PINMUX "peripheral". Some of those pins like SPI4 SIMO can appear on one of several actual pins on the chip. For example pin 25 can either be HET1_0 or SPI4CLK or a couple other things. Chose the one you want. It's very frustrating trying to find what you are looking for! The check boxes at the top seem to change a bunch of things at the same time, so I try to avoid them :-) To generate the code that does back into the git repo, use "generalte code" under "file". If you look at the generated code you will see stuff all through it that looks like this: /* USER CODE BEGIN (3) */ /* USER CODE END */ If you have to tweak some stuff (and I did) and you can put the code in between those comments, HALCoGen will not change it! Note for example that I actually replaced a lot of some of the SPI routines (see hcgExtras folder). I can explain why at some point when you are interested. But the main point here is that you have to keep the header and C files in sync between your build machine and your HALCoGen machine. If you change ANYTHING on either side, make sure they are the same on both sides. As I may have said, I use DropBox and have HalCoGen read and write its files there. Then I just copy from the dropbox directory to the IDE on the build machine and we are good, and have source control automatically for all the HalCoGen stuff. At some point, I may remember and talk about the HET code that HALCoGen pays some attention to as well :-) I hope this might get you started in looking at it at least.

Re: Initial playing with HALCoGen

Burns, Thanks. I installed HALCoGen last night after the meeting. 4.07.01 is the latest version. The second file is PacSat.dil, not PacSat.gil. I actually though that might be the output. So the output is the code found in the include/source files? I was expecting something more like a .xml file which is what the .hcg file is. I’m begging to understand it a bit better which is not to say I’m ready to lay down a system. Cypress Semiconductor has a similar system for defining their chips. Rest up this weekend. A long list of questions is likely to follow. 73, Jim McCullers WA4CWI From: Burns Fisher (AMSAT) via pacsat-dev <pacsat-dev(a)amsat.org> Sent: Friday, November 17, 2023 1:02 PM To: Pacsat Dev <pacsat-dev(a)amsat.org> Subject: [pacsat-dev] Initial playing with HALCoGen As we said last night, there are probably some HALCoGen things to change to get the s/w running on Blinky, aka Bob's Board.

At some point, I may remember and talk about the HET code that HALCoGen pays some attention to as well :-) I hope this might get you started in looking at it at least.

Initial playing with HALCoGen

As we said last night, there are probably some HALCoGen things to change to get the s/w running on Blinky, aka Bob's Board. This is not to tell you what, but just to get you started looking at HCG.

I have my monthly Thursday night thing today, so I won't be able to join. Next week is Thanksgiving, The next week I will be flying to India, and the next week I'll be in India. So it will be a while before I can attend, and I wll be very busy during all this. I also wanted to talk a bit because I'm not a big contributor to this effort. I'm ok to attend the meetings, but I will have a limited capacity to do much else because of other things I work on. So I can continue as is, but if that's not ok I'm fine with bowing out.

PacSat help commannds
by Jim McCullers 10 Nov '23

10 Nov '23

In Thursday night's meeting we discussed the current PacSat command process and how to obtain a command list while running. Below are the four help commands that list the available commands by category. Help List common commands Helpall List all commands Helpdevo List commands for software developers Helpsetup List commands for setting up new board As these commands are legacy, at some point we may want to consider removing commands that are not specific to PacSat and adding those we require as Chris and I have done.
