Posted on January 26, 2013 at 20:30Hello to all, I have a design where cpu has to transfer blocks of data to a uSD card working in SPI2 mode. My routine is : static void SPIblockTxDMA(uint8_t *SD_Buffer_Tx,uint16_t Len) { SPI_Cmd(SPI_SDMEM, DISABL...
Posted on January 11, 2013 at 10:40I tried to revive an older thread, but that seems not possible if it dates back before the last database meltdown ... Is there any simulation of STM32 MCUs available, specifically the F0 and F1 ? And I don't mean t...

Posted on January 26, 2013 at 14:13I want to add some features to my program where it remembers some settings, i want to do this by storing the values in the sram.But when i upload the firmware to the stm32 i need these values to be preset to a cert...

Posted on January 25, 2013 at 17:28I have spent a lot of time with the manuals for the stm32f4, but have had no luck finding the information I need regarding how long it takes to execute certain instructions. I assume add, takes maybe two CPU cycle...
Posted on January 25, 2013 at 17:12Hi All, According to the apps note AN4061, a page erase should only occur when one page is full. For instance, after the first run and the memory is formatted, page0 is marked as VALID_PAGE, and page1 is marked as...
Posted on January 25, 2013 at 06:39Dear All, I bought any product that contained STM32F103C8T6 48-pin mcu. I try to re-program it with my own hex file using Flash Loader Demonstrator and it can be wrote and verified correctly but the application can...
Posted on January 24, 2013 at 17:42Hello, I have an issue while 2 STM32F103REY are connected through i2c, 7bits addressing. It works good in the following cases: master transmitter master receiver for 1 byte master receiver for n bytes, n >=2 Not ok...
Posted on January 25, 2013 at 15:27I am acquiring data into one circular buffer while analyzing the data in the other buffer. The ADC switches back and forth between the two buffers. Do the two buffers have to be in separate memory blocks (0x2000000...
