I can c in RM0033 (Rev9) Figure 18, that PA2 is connected with low impedance to a diode to V_DD, if PA2 is configured as analog input...In Doc ID 15818 Rev 9 I see that R_ADC is at least 1.5kR...If I connect PA2 in analog mode directly to 5V: Would I...
Hello everyone,I am working on a system based on the STM32H747BIT6 MCU and do not plan to use the DSI interface. I have searched through various forums but still have some doubts about the proper power pin configuration when DSI is not in use. Here i...
I have a custom board based on the STM32F407IGT6 and I'm having trouble connecting via ST-Link (v2 clone) using STM32CubeProgrammer. It seems st-link unable to find the target mcu. I checked all SWDIO, SWCLK, NRST, VDD, GND connections with a multime...
Hello,I am trying to communicate with an SDI-12 sensor using STM32L072CZY6TR. I'm using UART half-duplex with the following configuration:Baud rate: 1200Word length: 7 bitsParity: EvenStop bits: 1My questions:Do I need a UART to SDI-12 converter modu...
My application senario: sample the sensor signal every second, and transmit through UART. to save power supply, I select ADC single mode, and used average as filter.void ConfigureADC(void) { ADC1->CFGR1 |= ADC_CFGR1_AUTOFF; ADC1->CFGR2 = (ADC1->CFGR2...
I've be trying to learn CAN for the past few days for a project using 2 Nucleo F103RB and 2 CAN transceivers. I made a very basic code using normal mode and without using RTR. Now I want to learn how to code using RTR, can someone help me please?(I ...
Hi all,We’re a small startup developing a commercial product using an STM32H755ZI, and we’re getting ready to ship. One of the key things we want to bulletproof before launch is firmware recovery for end users, especially in case the firmware upload ...
Hi, newbie here - I have some experience with the f4 series, but am working on a small project for which I would like to try a stm32u0 MCU. Looking at the stm32u031 20-pin TSSOP, I am confused by something. When I load this MCU in cubeMX, and tick on...
Hello,As per CM4 guide and TRM of Nucleo f446re,interruot vector table is array of function pointers and each pointer holds the entry address(initial address) of each IRQ_handler, Where interrupt IRQ_number is used for indexing.While debugging I fail...
So, I've got a circular transfer working, sending 24-bit words to a dual channel SPI DAC (with hardware NSS), paced by TIM2 and working well. For every edge of TIM2 a word is sent. Since this is a dual channel DAC, I would ideally like the transfer 2...
