Posted on September 29, 2016 at 01:50What would be the best way to reconfigure a pin from Input to Output and vice versa on the flight? The STM function HAL_GPIO_Init() is quite long so I would rather not use that function just to change a mode Inp...
Posted on September 27, 2016 at 22:26I've been looking in vain all day for specs on the analog input GPIO. Any help or referral to the proper docs would be much appreciated. It's referred to as 'high impedance', but 'high' is not quantified that I ...
Posted on September 20, 2016 at 10:35Hi, we have a problem in temperature AD acquisitions. The sensors are two Microchip MCP9700T-E/LT and are connected to ADC CH13 (pin &sharp18) end CH3 (pin &sharp26) through only a 22ohm resistance. The ADC is tr...
Posted on November 02, 2014 at 11:38Hello,I'm using an STM32F4 discovery board and I'm trying to control the DDS waveform generator chip AD9833 with it. I'm not very experienced with ARM. I have a AD9833 module like in the picture:http://www.ebay.co...
Posted on September 28, 2016 at 18:21Hi.I would like to periodically calculate CRC over code in Flash. Is it possible to see runtime the end address of the code located in flash? Most of the flash is free, so I will not like to calculate CRC over th...
Posted on September 28, 2016 at 13:29Dear all,I am trying to find a programming manual or a reference manual for SPBTLE-RF on the st website without success. I have found only a datasheet but nothing else.Any suggestions?

Posted on September 26, 2016 at 15:20Hi.I have a project working with a STM32F2/F4. I want to upgrade this project a bit, adding a CPLD/FPGA to do certain tasks that actually is doing the micro.We have done a small test and it worked with a SPI and ...
Posted on September 28, 2016 at 15:29I amusing the example program to run a single PWM and it works. All I am trying to do is run the CPU at a slower speed to conserve power. If I run it at 8Mhz with a pll setting of less the times 6 (so 48Mhz), the...
Posted on September 28, 2016 at 14:14Hi. I haven't figured out how to use the BSP_AUDIO library to record stereo audio from the blue line-in jack. This is a stereo jack according to the schematic. Thanks in advance.
