Posted on July 04, 2013 at 11:52I am a bit confused about the F303 op amps. If they can be used in inverting mode won't a positive voltage into the minus input result in a negative output voltage? Of course it won't happen because they are rail to r...
Posted on June 29, 2013 at 13:24Is it possible to use ADC without configure GPIO for AIN? For example, if the lines below are commented in the program, can ADC still work? // GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN; // GPIO_InitSt...
Posted on June 13, 2013 at 17:16HELLO I want to upgrade the fırware of my design by usb stick , I am using the example given with the discovery board where I need a binary image of my Project myproject.BIN, I am using keil so I can generate hex f...
Posted on July 04, 2013 at 15:18Hi,I work with an STM32F405 and i cannot use the CAN2. Now, I do some tests on the discovery board on an STM32F407. And with the same code developed for CAN2 used with CAN1 all seems good. I think, that I have forgott...
Posted on July 04, 2013 at 13:33Hi all, The documentation of the ''GetITStatus'' function, as found in the file 'stm32f10x_uasrt.c'', describes the functionality as follows: ''Checks whether the specified USART interrupt has occurred or not.'' H...
Posted on May 31, 2013 at 13:57I am working on a project using an STM32F103 with 768K of internal Flash. I can successfully erase and program the first bank of internal Flash, but am having problems with bank2. The problem seems to be that I am havi...
Posted on July 03, 2013 at 15:27Dear all I hope you can solve m problem. I need to configure the SPI2 on STM32F100V8 on pin PB12-14 in slave mode because I have a master board that communicates to other spi slaves. The SPI has the Clock normally Hig...
Posted on July 04, 2013 at 14:37Hi,I have an STM3220g-sk/iar demo kit. I try to configure the STM32F2 device to receive data with UART interrupt.I have the following codeint main(){ /* Reset all the ports to default values */ GPIO_DeInit(GPIOA); ...
Posted on July 01, 2013 at 12:55I have just created my own SDIO library for SD cards. It works pretty well but i noticed one issue with SDIO interface. I use STMF4 device clocked with 168 MHz. At 168 MHz speed the maximum SDIO clock frequency is 24 ...
Posted on July 04, 2013 at 02:16And how should I configure this pin?MISO is Input Pull UpCLOCK and MOSI are Alternate Function Push Pull CS is Output Push Pulland CD is ??????????? #sdcard-spi-cd-cs-mosi-miso-clock
