If that code makes use of port pins that correspond to Clock and Data pins in programming mode, there is a chance their values may not be 0, as necessary to enter programming mode. Essentials Only Full Version. Sep 18, 3: For the low Vusb problem, if the voltage of USB voltage is too low, the generated Vpp from the charge pump could be low so that it may have problem to program some old PICs which require higher Vpp. Thanks a lot for yours comments: It is perfectly okay to keep it closed source.

How do i check whether an I2C device works? In this configuration, if the chip is not empty, the code may start to run as soon as Vdd is applied. It has a nice device identification feature as well.

I am actually very interested in the dsPIC support of the programmer. Executable files that MCU programmers make 1. I checked with the author and Winpic is freeware but not open source.
So you are saying that Winpic is not open source. Originally Posted by wakaka. I change the 2 BC transistor and the capacitors, then it works nicely. Forums New posts Search forums. This code is prpgrammer by Sisco Media New media New comments Search media.

U only need to buy the PIC18F which has the firmware in it. CT measuring circuit with PIC 3. Maybe a missing driver.
