STM32G0 internal temperature sensor
Hello All,I need to read tempereture of mcu.But I confused about formula given at referance manual.which is below.Because there no data TS_CAL_2 val Thanks.Regards.EMRE

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...
Resolved! multiple SPI with DMA callback
Hey everyone,I cant seem to get separate callbacks going for my spi peripherals, each using DMA. Their both receiving data and by default seem to respond to HAL_SPI_RxCpltCallback. So whether SPI1 or SPI4's reception completes, HAL_SPI_RxCpltCallback...
STM32H743XI ADC DMA speed problem.
I am using STM32H743XI to capture a image sensor signal by using ADC and DMA.The image sensor signal is an analog signal following a 2.5MHz clock.I planed to use ADC and DMA to capture an image frame in a memory buffer.The size of the buffer is 268x1...
