ADC sampling time issue while external trigger with TIMER2 TRGO Update to send over USART

I am using ADC2 Channel 10 with external trigger TIMER 2 TRGO Update. Although I am viewing the ADC values over USART and it is sampled but the sampling time is not 2Hz. Which I set in TIMER 2 just to make sure that I can control the sampling time vi...

STM32F7508 change RTC after initialization

I believe I am doing something wrong. I read that to re-write to the RTC I will need to:1. Write ‘0xCA’ into the RTC_WPR register.2. Write ‘0x53’ into the RTC_WPR registerI found a function in the RTC file that is:#define __HAL_RTC_WRITEPROTECTION_DI...

I want to use the VCP capability for debugging.

I'm using the NUCLEO-303K8 board but I have the STM link/v2 and v3 to use too if that works better. I'm working inside the STMCubeIDE. The documentation that you can call up from within the application doesn't look like it matches the application, wh...

I tried programs with STM32F103C8 like ADC reading etc with MXCUBE. I would like to know how to program 16x2 LCD using MDK-ARM V5

Does anyone know the susceptibility of STM32F4 VBATT pin to ESD surges when changing out the RTC coin cell battery, or if there is some sort of internal protection against this happening such that an ESD protection diode would not be necessary?

How to implement VC0706 camera to STM32F4?

There are plenty of codes about VC0706 camera + Arduino. I tried the sample on Arduino and it worked pretty well. But I need to make this project with STM32. Any ideas how to implement and code VC0706 with STM32?

USB Host With Multiple Vendor Specific Devices

Posted on August 28, 2014 at 22:23I'm new to USB programming, and am having some trouble getting my head around the concepts involved.  Hopefully someone can have a look at what I think I need to do to meet my goals and tell me where I'm right and w...

In the datasheet for the STM32L151 is missing the value of the sampling switch resistance R_ADC in table 55. Does anybody knows the R_ADC value?

HAL I2C always sends 0xFF as first byte when responding to master using HAL_I2C_Slave_Transmit

I have an STM32G4 using the HAL function HAL_I2C_Slave_Transmit to respond with some data when requested by a master on the I2C bus. In the image below you can see the device sends 0xFF followed by the actual data it was meant to send (the data I am ...
