Posted on June 14, 2013 at 14:15I have write 8 bit value on port PA0-PA7, without disturbing PA8-PA15 in fastest possible way, also if interrupt comes & in that ISR PA8-PA15 are accessed they shouldn't make any error.I have edited GPIO defs of the s...
Posted on June 08, 2013 at 01:32 Hi, i realized a test source code for matrix inversion. I used the CMSIS DSP library which include arm_mat_inverse_f I also took a look at arm_matrix_example_fc... but i had 1 problem and 1 question. ...
Posted on June 14, 2013 at 07:20In old good 8-bit Architecture (AVR,PIC,...) CPU had a nonvolatile memory region to keep configuration parameters of the application that were persistent over reset. This region had a byte read/write access without er...
Posted on June 14, 2013 at 08:46Hi, The F4 series discovery card uses STM32F407. For our project we are considering using STM32F427. I'm wondering if they are pin to pin compatible? Thanks Michale #stm32 #discovery

Posted on June 11, 2013 at 14:12Hi! I have seen an earlier discussion with the device stm32F051 or F205 regarding the TS_CAL1 and 2 values. My question is, are these values applicable for the STM32F103 device? Cannot find any references to them in t...
Posted on June 13, 2013 at 23:45Hello, I have a new MCU customer in town that is looking for STM32F4-based information related to safety and robustness for medical applications within their Stem Cell production/separation device (FDA class 3 device)...
Posted on June 12, 2013 at 20:12Hello -- I'm trying to use the ADC functionality and am having some issues. I can get different values out of the ADC in response to changing inputs, but I can not get the EOC (end of conversion) flag to work, nor d...
Posted on June 07, 2013 at 14:56Hi,I tried to change my program from STM32F207IG to STM32F207IF and I have fail.In options for target I have changed the device to STM32F207IF.Then I go to Options for Target -> Debug -> Settings -> Flash Download. T...
Posted on June 13, 2013 at 16:56Hi,I'm using a stm32f4 discovery board. The data sheet says that my pins are 5V restistant. I have a device that outputs 5V ttl and I want to read this signal. It works, but does it reduce the lifetime of the processo...
