Reading data ADC MCP3208 - STM32F103C8T6

Hola comunidad!Estoy desarollando una etapa de un proyecto en la cual deseo adquirir los valores digitales de un ADC MCP3208 mediante comunicación SPI utilizando un STM32F103C8T6.En primer lugar, comparto el código que realice:/* Adquisición de datos...

stm32 CAN bus: A sends data to B nodes.

I have 2 nodes, A and B, they set filters for both, now A is sending data frame, B can receive the data from A. but A originally can receive data from B, but after around 1-3 mins the receiving data mainly from itself, minorly from B. but if i rese...

I2C timeout not working correctly

I have tried enabling the timeout function in the I2C controller by setting a value in TIMEOUTA and setting TIMOUTEN. I can see the bus working normally on a scope, then when I connect with the debugger ( no reset, no upload ), the halt causes the t...

Why does the Crystal Clock on STM32F103 have an offset and why is the microcontroller very sensitive to this offset?

Hi,I am currently having trouble with a Hard fault issue that I cannot understand and I was hoping someone might have come across a similar issue. I have a Crystal Oscillator with a 16MHZ clock at the input. I use the MCO pin from the microcontroller...

Any resources on how to ensure mechanical robustness using WLCSP parts?

I've been looking for specifications and/or white papers on the best practices for ensuring the WLCSP is able to be mechanically robust. Are there any documents that detail how much of a bend or flex is allowed in this type of package?I'm specificall...

How to apply compiler option like "__attribute__((section(".ram")))" to math.h functions ? Where are actually these functions ?

Hi there, I’m using an STM32L432 and I’m trying deep sleep with mbed RTOS. Using tickless mode I've been able to set deep sleep at 700uA usage. However, using threads increases the current to 3mA, normal sleep uses 5mA. What has caused the increase?

X-CUBE-EEPROM software package, fills in zeros into emulated EEPROM on every reset.

I am using STM32L476, and I downloaded X-CUBE-EEPROM software package, included it into my project and it works fine. But I am noticing that after every reset it writes dummy word of all 0. CRC + Vaddress +Data... all 32 bits are zeros.That write is ...

SPI only gives 16 clock cycles, but my data is 64 bytes

I am trying to communicate with a wifi module with stm32f769's spi interface. My data packet is 64 bytes, but the spi only provides 16 clock cycles, Hence the datapacket sent is invalid. Can anyone tell me what could be the possible solution for this...
