I encountered some problems. I used the capture function of F149 to capture waveforms and do decoding! I found that some waveforms in the TB0 captured waveforms could not be captured! I don’t know why...
As the title says. I am using STM to control SIM300 to send MMS. I don't know how to send the image file to the serial port. The image is obtained by the camera. Or from the SD card. Thank you....
The Concerto series is a new processor just launched by TI. Its structure is C2000 DSP+CortexM3 ARM. From my point of view, this device is particularly good for industrial control. C2000 is specialize...
I want to send many strings from PC: receive 8 bits at a time, then send 8 bits, receive 8 bits again, then send 8 bits again. But the program I wrote is like this. Sometimes the PC can receive 8 bits...
When using FDS9721_LP3 as a test PCB tooling, a switch is required to control multiple chips.
Because when testing voltage and resistance, the chip channel used is a PIN pin. I don't want to use a swi...
