I2C blocking function fails to output the expected outputs
I'm currently trying to learn about how the HAL blocking functions of I2C works on the STM32H7B3I-DK. However, the master device fails to receive any data unless HAL_I2C_Master_Transmit() is called before it.For example, the following code doesn't pr...
Programming using Keil uvision does not work vs STM32 programmer works
Hello all, I am using keil uvision to direct download the code in a STM32L552MEY6P MCU. My code just toggles a pin. The MCU is connected to a V3 programmer using SWDIO,SWCLK,NRST,GND and VCC. Every time I program with Keil, I am not able to initiate ...
Learning Materials for Beginners
Hello.Is there a complete course or book from start to finish for beginners on new ST programs? I want to switch from arduino.I found the book Carmine Noviello Mastering STM32, but it is old (2017-2018) and it uses an eclipse. I want to find a full-f...
What's a good stand-in development board for programming an STM32F722ZET6?
I need to collaboratively program an STM32F722ZET6, but do not have in-person access to the chip, and I can't find any development boards online that use it. I'm new to this, so I don't know how similar a stand-in must be for me to be able to confide...
Release version of KEIL project much slower than debug version on STM32F413 MCU, why?
I have developed firmware on STM32F413 with STM32CubeMX using FreeRTOS. I have several tasks and PPP connection over Serial (PPPoS). I am using KEIL IDE for debug and everything is OK in debug mode and after debug without resetting MCU. But when I po...
STM32F401VDT6 microcontroller :- PWM channel misbehaves after ESD (Electro Static Discharge) testing
We have custom board, having STM32F401VDT6 microcontroller on it. We interfaced a tricolor LED to the Timer 1 PWM channels (CH1- Red, CH2-Green, CH3-Blue). Recently we have ESD test, after that when we stop channel 2 PWM and started CH3 PWM that time...
