renew core and libraries/SPI with ArduinoCore-1.8.3 #50
Conversation
update core code based on ArduinoCore-avr 1.8.3
ToDo:
- remove HID.cpp, platform.h (this code is removed at arduino-1.6.6)
and add libraries/HID
- create LGT8x version DigitalToggle.h and DigitalToggle.cpp,
and remove digitalToggle() from wiring_digital.c
(this function is supplied from
https://playground.arduino.cc/Code/DigitalToggle/ )
mainly cosmetic changes. - add delay(100) to DigitalPotControl.ino - move NOP inside #if defined(__LGT8FX8P__) ~ #endif at transfer(void buf *, size_t count), virtually same code.

First merge jg1uaa, will take care the conflicts after. |

Oh, you have already fixed delayMicroseconds() in Wiring.h... sorry. I will fix this and push again. |
Improved accuracy in delayMicroseconds() (#51) * Update Arduino.h * Update wiring.c * Delete unnecessary files. * Delete unnecessary files. * Delete unnecessary files.
|
well, modifying delay() definition in Arduino.h is once cancelled (force-push is for that operation), but resolved wiring.c is still conflicted. It looks no code difference... |
|
I will once close this PR, resolve conflict and re-submit again. BTW, does anyone know how to write bootloader to LGT8F328P? |
|
Awesome, thanks!

I got SWDICE mkII Pro and I tried to repair my LGT8F328 board. I always perform read after programming FlashROM, but veriyfing itself make things worse... |
Did you use a LGT8 or an ATmega32 as ISP ? Personally, I was confused when I tried to make an ISP using an Arduino Nano, because there seems to be different ISP projects :
Also, LGTISP wants you to connect RESET to VCC on the ISP, while LarduinoISP wants you to connect a pullup resistor to SWC ... Very confusing. My working combination was : Arduino Nano + .hex from LGTISP + pullup resitor from LarduinoISP. Regarding the writing of the Booloader it works for me.
It also happen to me when I dump flash using AVRDUDE and my ISP. But when I upload a sketch using Arduino IDE and AVR ISP, it's ok. An other issue I encounter is that, once programmed using the ISP, the LGT board starts running the sketch at the wrong clock speed and needs an hard reset. |
I updated the instructions a while back. It works well using an lgt8f328p as ISP (but follow the instructions). Do you want to make a small "tutorial" of how to use a atmega nano as ISP? :) |
I have not tried with a lgt8 as ISP yet because i still have unsolved serial communication stability issues with my LGT8 :-/
Not yet. |
Isn't the source code just the same? It probably doesn't build for the Arduino nano because it requires a bigger serial buffer configured. It's defined in HardwareSerial.h as 64. Temporarily change it to 256 (in the atmel core) and it should work. |
Yes ! You are correct ! And updating bootloader and uploading sketches works. Now, just have to understand why |

@jg1uaa :
LGTISP/LarduinoISP dont fully implement the LGTISP/LarduinoISP implementation of |
|
@SuperUserNameMan I see. Indeed flash_read_page() in brother-yan's LGTISP looks something incomplete. https://github.com/brother-yan/LGTISP/blob/master/LGTISP.ino#L398 And I connect WeMos TTGO XI (aka OCROBOT ALPHA) with any writer as following:
This board can operate both 3.3V and 5V, but it annoys us how to apply the programming voltage to CPU. VIO pad is directly connected to LG8F328's VCC pin, I didn't use any pull-up resistor, is this mandatory? |
|
@jg1uaa :
According to the experience i read from other users, it is optional.
Actually, regarding usage with AVRdude, I've uploaded an improved version of LarduinoISP here : https://github.com/SuperUserNameMan/LGTISP Many functionalities are not supported ( There is also a discussion on the forum : https://github.com/dbuezas/lgt8fx-forum/issues/1 |
