Posted on June 01, 2015 at 20:05I've got a 23LC1024 it's a serial ram with spi capabilities http://ww1.microchip.com/downloads/en/DeviceDoc/25142A.pdf I'd like to be able to use it as an extension of my addressable ram on the stm32fxxxx. I have two ...
Posted on May 31, 2015 at 07:17Hi, I am using STM32f10B with STM32f103VGT6 on it. The problem is that the MCU is not working as per the program. It has a fixed GPIO high and they stay in the same state. I tried using coocox and IAR workbench. They ...
Posted on June 01, 2015 at 14:21Hello! I'm using STM32F407 processor. When I'm trying to send 1 byte via USART-DMA (for example 0x72) I get two bytes ''72 72'' in terminal.If I send two or more bytes everything is okay. If I send something from term...
Posted on May 27, 2015 at 12:11Hi, I am trying to configure the DMA based SPI communication for STM32F407. STM32F407 is the host controller(master), the slave is CC3100 WiFi module. I am implementing the DMA for SPI2. Following is my configuration c...
Posted on June 02, 2015 at 08:52 I'm using the FatFs library ver R0.10 to access the SD card. Here is my code: SystemInit(); USART_Configuration(); NVIC_Configuration(); /*-------------------------- SD Init ----------------------------- */ Sta...
Posted on March 21, 2014 at 10:34hello, I know that I should post this in Coocox forum, but I what to know if one of STM32 users faced this issue before: I have a strange issue with Coocox (COIDE V1.7.6), it may be a bug: - Optimization is set to -O...
Posted on May 22, 2015 at 23:48I'm reasonably competent in using CubeMX, STM32F4xx with IAR. I added the SDIO driver for micro-SD cards, via the latest HAL libraries that CubeMX utilizes. I have this ID'ing and doing read/write at the driver level...
Posted on May 30, 2015 at 14:27Hi, I an laying down some decode logic for 2 x 16 bit SRAMs using Chip Select NE1, by bus configured for 32 bits 12 address lines. If I Write using address 0x60000000 the NBL0 and NBL1 signals are both low during the N...
Posted on June 01, 2015 at 22:00 Hello, I working with STM32F3, and my goal is to feed in an external voltage into COMP2 (non-inverting input) compared against another constant analog voltage (inverting input), in order to produce a calib...
Posted on June 01, 2015 at 17:09Hi all, i'm new to cortex M4 STM32F4 processor and i have some problems with external interrupt handling and internal timer interrupt. Currently i'm trying this code on a DISCOVERY F4 board (with STM32F407) and i'm tr...
