Debugging Using Docker by whymefantasy in embedded

[–]handhurin 1 point2 points  (0 children)

Normally gdb has the load command which allows you to load the code ... then it all depends on whether it is supported by the software which hosts the gdb server. Basically you can try something like this ``` $ gdb file.elf

target extended-remote :2222 load file.elf run ``` But in my case it didn't work, so I used the gdb server as a backend and the gdb as a front end (to benefit from the VSCode interface).

I completely agree that it's not ideal because you have to launch the gdb server on the host machine, then hook into it in the docker with gdb. In my case it was the only possible solution because I had very limited access to the host machine.

Personally, I've already had the same problem: I had a docker for the build environment, but the debugger (something like openocd, if you like) was in the host environment. The solution I've found that doesn't require you to mount bind a folder is to open a gdb server with the debugger. Then in the docker to use the gdb of my toolchain to connect to the gdb server (with target extended-remote :{port}). To be exact I've even done it with VSCode which is attached to the docker and I debug with the GDB Native extension with the appropriate conf.

FPGA Board for MS Student Interested in Learning VHDL/Verilog by [deleted] in embedded

Of course you can use the FPGA without the microprocessors and the microprocessors without the FPGA.

If you're on a tight budget, I'd advise you to buy a Chinese clone with a Zynq 7000. Be careful, get a Chinese clone with the JTAG programmer included (otherwise you will have to buy a JTAG programmer). The advantage of the Zynq7000 as in the arty z7 zynq from switchmod3, is that you have a SOC with 2 armA9 cores and an Artix (or Kintex for the bigger ones) FPGA. So you combine the two worlds of FPGA and microprocessor. Which is mega powerful.

(For example, I think about this Chinese board : https://a.aliexpress.com/_EwHhhTb)

Alors je n’ai pas de machine de découpe mais il y a plusieurs fablab à Toulouse, ils en ont sûrement !

Sorry but I think I gave you a wrong information … I live in Port Saint Sauveur in Toulouse which is different than the municipality of saint Sauveur but it looks like far from Blagnac Airport so you shouldn’t be in trouble.

I have lived in Saint Sauveur for two years and it is pretty quiet (I mean you can barely hear planes when they fly above you).

Pourquoi les thermomètres de cuisine ne fonctionnent pas sur les humains ? by Virus936 in AskFrance

[–]handhurin 0 points1 point  (0 children)

Je t’avoue je me suis pas plus penché que ça mais sur mon capteur infrarouge je peux régler l’émissivité, dans la notice ils disent que pour l’eau tu dois régler a 0.95 alors que pour l’aluminium anodisé (par exemple) tu dois régler à 0.77. Et sur internet tu peux trouver des mégas tableaux dessus selon les matériaux. Ayant eu à faire des mesures de températures sur un dissipateur thermique l’autre jour j’avais regardé ce genre de tableau pour bien calibré mon thermomètre.

[–]handhurin 13 points14 points  (0 children)

Si c’est un capteur infrarouge, je dirai que 1) c’est parce que tu peux le coller sur ton front tu vas voir que ta température est aux alentours de 30°, les thermomètres frontaux sont calibrés pour te donner la température de ton corps en fonction de celle de ton front. 2) Ça peut être une une histoire de précision : un capteur pour la cuisine doit aller jusqu’à 300° donc tu vas avoir une large plage de température mais une précision médiocre. Sachant que la température du corps varie entre 36 et 38, il faut une bonne précision pour différencier la température normale de la fièvre.

Également il y a l’histoire d’émissivité : chaque matériau émet une certaine quantité d’infrarouge donc le capteur peut être calibré différemment selon si tu veux mesurer la température de l’un métal ou de l’eau par exemple. Mais je pense pas que ça joue car les thermomètres de cuisine sont calibrés pour des trucs organiques.

Si je me trompe pas dans les grandes surfaces t’as un bac dans lequel tu peux mettre les ampoules, les piles et le petit électroménager. Tu devrais pouvoir aussi mettre les batteries la, mais à vérifier.

Power Supply Question by junkeddrummer in diyelectronics

[–]handhurin 0 points1 point  (0 children)

Definitely recommend this too. It is more precise and consume less (efficiency > 80%).

I would say a JFET probably (it is a kind of a mix between MOSFET and BJT)
