stcgal patched to support STC8G, STC8H, STC8A8K64D4 and STC32G.
This project has been merged into STCGAL and I now contribute to its maintenance. You should now use https://github.com/grigorig/stcgal instead, or just pip install stcgal.
I'm trying to set the reset_pin_enabled target option.
However it does not ever appear to be set to true after repeated power cycles/isp reads.
I do know that options like eeprom_erase_enabled persist after erasing chip and so remain true until cleared.
I also tried driving the pin high anyway but it does not seem to force a reset.
I have a CP102x based usb to uart with output DRT pin which I inverted with 2N2222 transistor.
This makes the reset pulse active high, but again no reset appears to occur.
What am I missing?
According to its datasheet, microcontrollers part of the STC8G family have an integrated high-precision internal IRC oscillator, which can be used in two frequency ranges depending on the content of the IRCBAND register:
The adjustment range of the 20M band is about 14.7MHz to 26MHz (LSB=0).
The adjustment range of the 33M band is about 24.5MHz to 42.2MHz (LSB=1).
However, I cannot use the upper frequency band via frequency trimming using the -t 30000 parameters.
I read in the FAQ that the safe range is 5MHz-30MHz. Can this range be extended somehow?
Hello,
I am using a PCB that contains the STC8A64D4-LQFP44 device. The board contains a FTDI device (FT234XD-R). When plugged in the FTDI chip is powered from the USB but this rail is not shared to the PCB. I am able to program the board using a windows machine and the STC-ISP software by pressing the download button and then powering on the main part of the PCB. When I try to program using STCGAL (and make files from UNI-STC project) it sits at Waiting for MCU endlessly. Is there any suggestions you can provide on debugging this? I know the STCGAL installation works as I can program a demo board with the STC8A64D4-LQFP48 on it.
Thanks in advance.
