I'm trying to configure Bank 1 of the FMC in Mode 1 (SRAM). I'm nearly there but ran into a frustrating problem, where it insisted on writing 64 bytes despite me setting the FMC's MWID register to 01 (16 bits) and using a uint16_t* in C to perform th...
The STM32469I-EVAL has 128Mbits NOR FLASH (PN: S29GL128S90FHI0) and 128 Mbits SDRAM (PN : IS42S32800G-6BLI).There is 512Mbits FLASH version of the S29GL family but the access time is higher. Is it an issue for the STM32F469 ?Which requirements have I...
Hello STM Community!First of all, I would like to thank you to read my topic and enter in this discussion.I'm new with STM32, and it's the first project of mine that I really need to worry about energy comsuption.In my project I have sensor that I...
Hello,I am looking into the ROM tables on STM32F439ZI. TPIU (0xE0040000) class type is 0x9, in its romtable, there are two entries:0xb, which is strange because it is marked as present (0b11) but offset is zero which is prohibited.0x1, which means pr...
Hi,i'm unable to run the NFC poller on a X-NUCLEO-NFC05A1 on a raspberry running Raspbian Lite.I get the following error:"Error: writing interrupt pin to gpio export file"Could someone advise please?Jacopo Chicco
HI There,I want to access multiple SPI slaves at the same time.They all share the same CLK , the same MOSI pin and the same CS.Therefore, I wrote two code sections which basically should do the same.They kind of work, but they both have the same Prob...
Hi, I want to use USART in interrupt mode in stm32f429 evaluation board.I saw the demo example UART_Hyperterminal_IT, but I didn't understood why they are calling HAL_UART_Receive_IT() function if we are using USART in interrupt mode not in polling m...

Hello.I'm trying to get I2C working to read BMP280 sensor data. This is code I written so far: GPIOB->CRL |= GPIO_CRL_MODE6; //set PB6 as output with drive strenght to 50Mhz GPIOB->CRL |= GPIO_CRL_CNF6; //set PB6 to open-drain alternate funct...
