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 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...
