Resolved! How to configure HW for periodic burst of pulses?
What is the best way to create 480 1us pulses (to clock an A/D) every x seconds?Can this be done with one timer?

Why am I getting "No Synchronization" when trying to use trace on M4 core of STM32H747 to write to "Debug (printf) Viewer"?
I'm working with the STM32h747-DISCO with Keil Development tools and an ST-LINK debugger, and I'm trying to use the Debug (printf) Viewer. I can get it to work properly on the M7 core, but am getting "No Synchronization" when I try to use the M4 co...
DMA of continuous mode ADC triggered by event out of Timer3???
Hello all...I have 6 channels of A/D that I want to sample continuously for 480 samples total. I want these samples to be triggered on the rising edge of event out of Timer3 every 5 seconds...I have tested Timer3 using toggle and GPIO and it looks a...

SPI hard NSS and multibyte transmission
Hello,I am using bare metal STM32G441 SPI (no ST HAL or LL). It has been a very tiresome dilemma with the chip select. If I use the hardware NSS (Motorola mode) then I get a pulse after each byte. If I use software NSS then the last bit gets crippled...
Resolved! Why i didn't get 50hz frequency when i set internal clock(APB1 Timer clock) is 20mhz?
Board: STM32L496ZGMy requirement - 2ms dead time Frequency - 50hz and Internal clock is 40mhz.In 40mhz (internal clock) i got expected frequency (50hz) using Prescaler = 80-1 Peroid value = 10000-1PWM Counter =5000-1 Then, i redu...
ATMEL mXT336T i2c driver for STMH7xx MCU
I am using STM32H745BIT6 MCU with Orient 5.0 inch Display (AFY800480B1-5.0N12NTM-C) that consist of CTP Chip from "ATMEL MXT336T".Can anyone share I2C driver for same?
Resolved! ADC register ADRDY never sets when I enable the ADC, so it keeps waiting there to start STM32F303RBT6
Hi all, I have this problem. I want to start the ADC of my microcontroller, and following the reference manual it says I have to wait until the ADRDY register is set by the hardware to continue and make conversions, but that register never sets. This...
Resolved! BOR Ultra Low Power Enable - STM32U575
I am trying to test out the Stop2 mode on the STM32U575 (Specifically the NUCLEO-U575ZI-Q) but am getting very high currents in the mAs. I am putting the device into Stop2 mode with the MSIS as the system clock at 4MHz. I then set the Power Regulator...
