Hi,I am using a SIM7080G module along with the eSIM model ST4SI2M0020TPIFW, and when I use the AT+CCID or AT+CPIN? commands, the module responds with "+CPIN: NOT INSERTED". I have followed all the steps in this tutorial to activate it, and I managed ...

Hello, I am designing a device that will have an STM32L4 or maybe an STM32U and will communicate with an ESP32 for internet connectivity. However, at some point, I would like to update the firmware remotely, and have the ESP32 stop executing its conv...

Hello,I'm starting a project with an STM32F429IIT6 MCU, but I have a doubt. The project will have a display (I haven't decided yet if it will be 4.3" or 7"), and I'll be controlling the display with the MCU's internal TFT controller using TouchGFX. S...

Hello everyone,I plan to use an STM32L4R7xx MCU in a project and I want to employ capacitive touch sensors. I've read that the TSC module can assist with this, and I should only design the buttons on the PCB. However, I've also read that water and hu...

Hello everyone,This is the first time I will be using TouchGFX, and I'm not sure if what I want to do is possible. Additionally, considering that the MCU has only 64k of flash and 40k of RAM, is this integration feasible?.

Hi @PGump.1 and @Andrew Neil , your answers were very helpful. I will try to implement the two methods you mentioned, as the ESP32 needs to send the update to two STM32s, and I'm not very sure which method would be more effective. Thank you for the...

Hello @Stassen.C ,Thank you for the response. I'll look for an IC that can assist me with the touchscreen sensors and the STM32L4+Regards.

Hello @MM..1 & @Tesla DeLorean I've been reading the documentation, and you're right; there's very little flash memory and RAM to use it with TouchGFX. What other GUI development tool that consumes fewer resources could you recommend? Do you think I...

well... I will use a pixelated display, the circuit will be powered by a 3.7V @ 4700mAh battery and I think the fps are a debatable issue, basically because if I use a tft display driver it will depend on the frequency of the communication bus and th...
