SOLVED: was a problem with NSS pin, the code is GPIOA but NSS is GPIOB... thought I corrected it Hello, I am trying to read register on a RFM69HW transceiver, it uses SPI.I have used this module extensively. Works perfectly on arduinos, esp, and othe...
Greetings,I want to compile the BLE Transparent Mode sample from the Cube (Version: 1.13.1Build: 17479_20230728_0839 (UTC)) for the STM32MMB module that has a different UART port from the default which is PB6/7. Our design uses PA9/10 because we nee...
Hi STM forums,I use a stm32f205rct6tr for this projectin my project i need to send 1024 clock signals to the slave, the message inside is not inportant.but after sending around 125 bytes it stops debugging entirely, i checked it out with the oscillos...
In the ATM32H747XI datasheet Table 9 on page 89...As I read this table... Examples are...Pin Name PA1 Alternate Function AF1 = TIM2_CH2Pin Name PA2 Alternate Function AF2 = TIM5_CH3Question 1:For PA0 AF1, there are two functions listed... TIM2_CH1/TI...
Hi community. I would like to know if reading the internal temp of the mcu (using the right channel of the adc) can give you an accurate idea of the temperature of the pcb where the mcu is mounted.Is it accurate this temp?Is it sensistive to other ef...
Hi I have pin PA6 setup to interupt on high and low levels. I have done the following:GPIOA->MODER &= ~GPIO_MODER_MODE6; //PA6 as inputSYSCFG->EXTICR[1] &= ~SYSCFG_EXTICR2_EXTI6; //PA6EXTI->RTSR1 |= EXTI_RTSR1_RT6; //enable rising edgeEXTI->FTSR1 |=...
Hi,I have inherited a project that utilizes Nuttx RTOS. This project is to change out the LCD display due to EoL. We are changing from Renesas R61580 Driver to Ilitek ILI9341. The existing driver is hooked up via 16-bit MCU command via the FSMC, with...
Hi everyone,I am encountering issues in sdcard initialization on my custom board.I am getting SDMMC_FLAG_CTIMEOUT error in SD_PowerON once the first CMD8: SEND_IF_COND is sent.Looking at signals and comparing with an identical custom board, you can s...
Hello,I've seen the AN4229-how-to-implement-a-vocoder-solution note, which talks about support for G.711 and G.726. Does anyone know if anything is available specifically for G.722?Thanks
