Posted on November 07, 2011 at 22:59When single stepping through the initialization commands for the SDIO card socket (STM3210E) I notice that ACMD41 always returns a command CRC error flag. The ST example code specifically ignores the CCRC FAIL fl...
Posted on November 17, 2011 at 12:20Unfortunately I do not own an oscillope nor a logic analyzer to see this.I'm having some problem using the SPI controller to communicate with a sensor.I've managed to get some data, but not in a consistent way.In ...
Posted on November 17, 2011 at 15:38When try to access to SRAM through FSMC (SRAM example from IAR 6.1) I don't see any address on ADDRESS 7:0. Only high frequancy (> 10 MHz) peaks and splashes. With ADDRESSes 20:8 all OK. With DATA BUS all OK. Re...
Posted on November 15, 2011 at 14:41I have been able to successfully setup the ADC3 to set the SR, AWD flag when an input exceeds my threshold set. What I am now looking to do is put the processor in sleep mode (via __WFI();) and then have it wake ...

Posted on November 17, 2011 at 12:06Excuse. What means PC 1 ADC123_IN10 in the table of gpio of stm32f103ze (arm fly).Means that the pin PC1 is the Pin of the ADC channel 10?
Posted on November 17, 2011 at 10:13Hi all,I'm using StdPeriph lib and saw there is such code in stm32f10x_adc.c:#define CR2_EXTTRIG_SWSTART_Set ((uint32_t)0x00500000)and /*** @brief Enables or disables the selected ADC software start conversion...
Posted on November 15, 2011 at 14:39I programmed the systick timer in order to get 1ms delay but I seem to get a 10us delay instead.From the reference manual RM0008''The SysTick calibration value is set to 9000, which gives a reference time base of ...
Posted on November 16, 2011 at 21:44Hello, I want conect a MMC/SD-Card to the SDIO interface with the configuration for ''SDIO_BusWide_1b''. (STM32F207) I have never found a demonstration how I must connect the wire and witch wire I must use. Now, I...
Posted on November 16, 2011 at 12:45Hi, I have my STM32F103RB connected to an ADC via SPI1. I read my ADC in two modes, in single shot mode I do SPI transfer in polling mode and all works well. In continuous mode I need to read data from ADC every 2...
