Blackmagic + gdbgui

 Sometimes it really helps to have a nice GUI for GDB

Finding an IDE that supports *correctly* remote gdb debugging as used with Arm or RiscV boards is difficult.

There is one option that seems to work ok : gdbgui

The principle is that the UI is actually your favorite browser

How to start it easily with the backmagic ?

1- create a blackmagic gdb init script

target extended-remote /dev/ttyBmpGdb
monitor connect_srst enable
monitor swdp_scan
attach 1
load
compare-sections
set mem inaccessible-by-default off
set confirm off

2- start gdbgui through a small shell script

#!/bin/bash
export F=$PWD/$@
echo "Loading $F"
gdbgui -g "/home/fx/Arduino_stm32/arm-gcc-2020q4/bin/arm-none-eabi-gdb-py3 -x /home/fx/blackmagic.gdb ${F}"

(you'll need to adapt those 2 scripts for your configuration : path to gdb, path to blackmagic.gdb, device to use etc...)

then
bash ~/gdbgui.sh myelf.elf

and it starts. 

A small warning, i have to go to the output panel and press enter or else it gets stuck waiting for a key press

Component tester with STM32 : Part 1 ADC, Resistor

Image
I was always  fascinated by the so call "transistor testers" that identify and report pin out, features of pretty much whatever you throw at it. They are based on Atmel 328p chip, the same as arduino nano. So why not do the same thing with a STM32/Bluepill ? The STM32 is faster, has a better ADC accuracy, more memory, can do float etc... and is not more expensive. Warning : I'm doing this for fun & to learn, it might contain error & plain misunderstanding So, i watched a couple of video on the general principle on how they work. This is not a "port" but a rewrite from ~ scratch. When something is weird, i check what the original one does for comparison. Measuring resistance So first thing first :  Resistance & Capacitance. These 2 will unlock the other ones. So how do we measure resistance ? What we do is a resistor divider with a know resistance value: Measure = Vcc*(RtoTest/(RtoTest+Rknown)) As far as the ADC goes, it means ADC=

Fixing the INA3221

Image
It 's not too complicated to change the board we have seen  previously . You 'll need to cut some tracks, i did it with a dremel and i'm not very handy, so you'll do better. Red =Cut tracks Blue = Add wire 1- You'll need to separate the bottom connector from the ground, cut the 3 connectors BOTH SIDES. 2- Remove the small red area below the middle resistor to isolate each channels from each other Last, connect right side of each connector to the now isolated pad. Mine looks like this after the operation (ugly i know): Be wary of the small track on the left connector that leads to the left side of channel3 resistor. I cut it while isolating the right pad. Now it works, we can go back to the charger.

INA3221, weird wiring

Image
Continuing my "smart" battery charger, i've finally received the INA3221 module. It is the purple one you can find on ebay for ~ 5 bucks I soldered a couple of pins to be able to connect it so that i could test it and something immediately caught my attention. It is supposed to be a high side current/voltage sensor, typically in a setup like that : So you can measure the voltage supplied to the load, and the current going through it. Now, let's have a look at the module, look at the top of the following pic, where the sense connectors are. CH3/GND/CH2/GND/CH1/GND ? Wait ? What ? Yes, all the IN- pins are connected to ground, so it is a bottom current only sensor. Additionally, the - side of the shunts are ALSO connected to the ground, no only the connectors. The actual layout is like that : That raises two problems :  The voltage is meaningless as we are only measuring Current x ShuntValue, not the supply volt
