ST7735 1.44 TFT screen not work with stm32f030c8t6

I'm using stm32f103c8t6 to control tft screen. I tried to use stm32f030c8t6 to conrol tft with same library but screen is always black. What can be the reason ?

Bootloader NACK on some chips but not others (not electrical problem)

We are using stm32g431c8t6 and firmware update is performed by another MCU placed on the same board, via UART bootloader.During development everything was fine - but after production, on some chips (~10 out of 50) bootloader behavior is undocumented:...

Have you noticed the Binary mode of RTC v3?

According to AN4759 , the RTC v3 (or, as they call it there, RTC3) - in 'G0, 'G4, 'L4P5, 'L41x, 'H7A3 and some of the more specialized series, has a Binary mode as an alternative to Calendar.JW

Resolved! RM0455 STM32H7A/B: Reset state of SYSCFG_PMCR incorrect?

RM0455, rev. 6, says reset state of SYSCFG_PMCR is 0x0F00 0000.But STM32H7A3ZIT6Q, rev. Z, shows 0x0300 0000 instead, i.e. PC2 and PC3 switches closed. not open. Does this depend on package as PC2 and PC3 are not bonded out for this particular packag...

Not able to update internal RTC in STM32F373

Hi, I made a project for only internal RTC. It worked with LSI and not with LSE. Then I integrated RTC in current project which has various other features. It is not working. I am getting zero readings. RTC initialization, get tim...

No device found on target ERROR

I have a STM32NUCLEOF411RE. It was working well until today. Now my pc can not recognize it. It says "No device found on target.". Also when I connect my board the processor becomes too hot in a few seconds. However, when power it with 5V it does not...

Issue in STANDBY Mode in stm32f746g discovery board.

Hi everyone,I am trying to implement the STANDBY mode in stm32f746g board using the system wakeup pin PI11 (user push button). The issue is that once I press the button, the controller automatically wakes up from the STANDBY mode.I have attached my c...

Resolved! Dear Support, Please help to check and advise if the part number below can be interchangeable? The suffix "B" denotes as Internal Code. Can I use STM32F100R8T6B as a replacement to STM32F100R8T6? STM32F100R8T6 STM32F100R8T6B

STM32H743 Interface with external ADC & DAC for closed loop control

I wish to build a classical closed loop controller based on a STM32H743 interfaced via SPI to an external 16bit ADC and to a 16bit DAC. The MCU is supposed to read an ADC sample, feeding a controller routine (for example implementing a standard PID c...
