Posted on June 06, 2012 at 07:36Hi. I need to read a digital signal coming into an STM32F100. Timing how long the signal is in a low state and also knowing if the counter overflowed would give me the two pieces of information I need (value of the da...
Posted on September 06, 2012 at 10:49ello,I sometimes have problems with blocks which are written completely wrong onto the sd-card. Workaround: actually I check the written data again by reading the same block from SD-card and check the both buffer...
Posted on September 03, 2012 at 18:08 Hi, I am using the software example 'MassStorage' , the IAR compiler and the STM32F103ZE kickstart board for development. I wanted to add some functionality which requires consecutives reads from ...
Posted on September 06, 2012 at 07:13I'm having some difficulty communicating with a TI INA219 using an STM32F407VE and I2C1 on PB7 and PB8. Sending data seems to work just fine, but receiving it does not. Namely, my EV6 (I2C_EVENT_MASTER_RECEIVER_M...
Posted on September 05, 2012 at 16:30Hi all! The software design process we use requires that every piece of code is heavily tagged with references to the original programming manuals. Sometimes these tags are added during code reviews, etc. The que...
Posted on September 05, 2012 at 03:07Hi!Is there a way to clock (only) USART1 using a (variable) external clock of 1 to 12 Mhz?Also, is there a way to clock USART2 using another clock source than system?Thank you!
Posted on September 03, 2012 at 09:05Hello everyone,For a project, we try to debug STM32C-Eval board without SWD/JTAG standart board. We have an *.out file and we want to download this file. We want to implement a C/C++ program instead of SWD/JTAG. ...
Posted on September 04, 2012 at 02:47Hi all, I am new to programming. I wanted some help regarding rtc coding. I am using stm32l1 discovery board(and IAR workbench), and want to generate interrupt after every 2 mins. I think using timers for this wi...
Posted on September 04, 2012 at 00:42Hello! Sorry for the new thread I'm new here, and I ran into a strange problem... I have a board with an STM32F103C6 micro, and I'm trying to switch the uC to use the on board HSE crystal (12MHz) instead of the ...
Posted on August 29, 2012 at 16:40I need to measure the averige a signal is low using the ADC. Is there a way to connet the adc to a timer? I have nott been able to figure that out, so insted I have tried the folowing... Start systick at 1ms, that c...
