Hi TeamWe are currently working on ST MCU PN: STM32L431CCY6TR in our new project. Thus, I would like to check with ST whether this part is OK to be Conformal coated? The reason is, our PCB will need to be conformal coating after all the components ar...
Hello,We are facing RTC Drift as mentioned in previous question, So We have some queries regarding PCB Layout.1) GND of Crystal's Capacitor is connected to nearest GND Pin of STM32L412, should I connect this MCU GND Pin to Common GND Plane?2) How sho...
I'm struggling to connect directly my nucleo u575 using an external stlink. I have opened JP2, closed JP1. The pinout of connector CN5 is the following: 1 Vdd, 2 SWDIO, 3 GND, 4 swclk, 6 SWO, 10 target reset. The pin out of the stlink is 1 Vcc, 2 SWI...
I entered an inifite loop at the HAL_RCC_OscConfig (l 29) of SystemClockConfig() void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulato...
Table 3 of DS12900 - Rev 6 shows a max voltage of 5.5V, which doesn't make sense, unless I'm missing something very important.Is this just a typo? Seems like it should be on the same line as the GATE pin or IN_GD.Thanks
I have a board based on the STM32L4R9 Discovery board. A key difference is that my board has Micron external flash (MT35XL512ABA1G12-0SIT) rather than Macronix (MX25LM51245GXDI0). The ST-LINK programmer fails to erase my flash, presumably because the...
I have a custom board powered by using USB, if I need to program a firmware by using the SWD feature in the ST-Link V2 Probe, may I connect just following 3 pins (without VDD) ?- TMS_SWDIO (pin 7)- TCK_SWCLK (pin 9)- GNDDo I need also to connect VDD ...
Hi,I am trying to implement a method of reusable code starting with STM32 projects. I have multiple micro controllers (F4, F7 etc) that will need to run the same application code. As STM generate the Drivers/HAL for me. Would I need to write API func...
Hello,I am working on a custom board design and we are looking into using the STM32H7B3IIT6 or the STM32H7B3IIT6Q. The main difference I've seen between the two is the Q-version removes some of the IOs to add an SMPS. I am trying to determine if that...
Can I know the program board(development board) and programming code of STM32L010C6 microcontroller please? Also can I get the circuit diagram of the air conditioner machine. I only found the block diagram.
