This is Hester, from TES procurement. TES is taking over 3M Touch business. ST has some parts dealing with 3M Touch. Could you find out ST part list for SCT EXII-ASIC-C chips that 3M Touch normally purchases? We do need the parts to build up our bom.

3M informed that ST agent contact window is Dave Massicott from Synergy, Inc. I've emailed him twice, and haven't got any feedback yet. My duty is to find out the related part data as price, LT, MOQ. As I am in Taiwan, I also need to know TWN agent f...

RM0440, Rev 4, STM32G4 Reference Manual - Section 27.5.28 - typo

Page 997 - the title of section 27.5.28 should be HRTIM timer x output 1 reset registernot: HRTIM timer x output 2 reset register

RM0440, Rev 4, STM32G4 Reference Manual - Table 222 - typo

Page 890, Table 222, hrtim_eev3 is in the table twice instead of the second one being hrtim_eev4.

RM0440, Rev 4, STM32G4 Reference Manual - Table 221 - typo

Page 884 - last row - corresponding to EE1FLTR[3:0] = 1111 it should say Table 225 and not Table 19. Hopefully, you can make it a "click to jump to the table" link.

STM32G474 - DS12288 Rev 4 - What is EVENTOUT in Sections 4.10 and 4.11

Section 4.10: on pages 58:73, Table 12, every pin has "EVENTOUT".Section 4.11: on pages 74:80, Table 13, every row has "EVENTOUT" under AF15.I found this: https://community.st.com/s/question/0D50X00009Xkc2bSAB/what-is-the-eventout-cortex-output but i...

Resolved! What is the maximum clock setting for the APB on the STM32H743 EXTI_LINE_0?

Dear friends,I have been using the STM32H743ZI in three phase power supply project and the controller is responsible for the zero crossing detection of the three phases. To do this I use PB0, PB1,PB2 set up as EXTI inputs 0,1,2. Mains frequency is 50...

about HAL_UART_Transmit when Paired device is gone

I am making L031K6 mcu sensor. This sensor regulary sense some adc data then send the data to Android device by BLE.and I am using HAL_UART_Transmit() for sending message to android by BLE.but when android is missing, my MCU runs bad. so I guess HAL_...

Dear All ,I used the STM32L4 series controller in that I want to write one string in Non-Erasable memory location, also I want to change it using programming. that is changing of string will be done by my program and stored location will be Non-Erasable

Wants to stored that string in non-erasable memory location . when I off the power supply it should be present .also I want to change that string at running the programI have search on netAny help will be highly appreciated.

Resolved! I work on a timer application for a STM32F103 MCU. The goal is to time pulse signals. My question: what timer input channels are connected to what GPIO pins (PA.02, etc.)? I assume there is a table in some ST doc. Can you please point me to one? Thanks!

Reading AT command response

Hi, I would like to read AT Command responses back from my ESP2866, as I want to check whether the response is "OK" or "Error". I made a function as below but it doesn't work properly.The plan is to send AT commands on USART3 and right after that, re...
