I grab close to everything from Farnell Element 14 ... here the french page with 536 ohm , you can get all quantity you want :) https://fr.farnell.com/w/search/prl/resultats?st=536+ohm But bigger quantity is better...

Yes Frank , the resistor value are the same when you add more stage ( 1 x 536 and 1 x 270 ohm ). Just bad that i cant help for the VGA code on Teensy :) , i was more involved in STM32 in the past , and the registers /...

Hi Frank , this schematic is my R2R DAC for get better colors. The original pin description is on Jean Marc Github for the VGA library here : https://github.com/Jean-MarcHarvengt/VGA_t4 And the pin-out don't have...

Hi Jean Marc :) Yea , 12bit VGA can be fun to try , but the thing with FlexIO without the right pins coming out will be tricky ;) I get one of the PMOD Digital Video Interface , as you probably have see , they are not...

Hi :) For HDMI it can be possible to use the PMOD Digital Video Interface ... You can get it here : https://1bitsquared.de/products/pmod-digital-video-interface Cheers.

Hi Jean Marc , I just fond out for audio , i activated the commented MQS in your code. But it was allot of noise , so i made a filter and now everything goes well ;)

I forget to ask you about audio :) On github i read that you use MSQ for audio. Do you use MSQR , MSQL or both ? If i understand correctly , all i have to do is to connect a little audio amplifier on this pins (10 &...

That's it :) on gameboy emulator : myTimer.begin(vblCount, 40000); <--- i set it to 20000 and it's more like the expected speed :) VID_FRAME_SKIP 0x1 give a little boost too .... To test the result speed i have test...

Hi , i tested some of the emulators , they are working up to one (.... problem.....) , It seems that all emulators are slower than normal , can it be that the T41 is not set at 600Mhz ? In the Arduino IDE it's check...

I found why it was not working correctly :) It was here ... #ifdef HAS_T4_VGA #define PIN_JOY2_A1X A3 #define PIN_JOY2_A2Y A2 #define PIN_JOY2_BTN 14 #define PIN_KEY_USER1 22 #define PIN_KEY_USER2 ...

Hi , i have do like you said and everything is working up to the joybut and the 3 user keys.(they work on a test sketch i have do just for testing the analog joy and the buttons). The Emulators don't react to the...

Hi , thanks for all this information's :) I use the ILI9341 , so i will then not connect the MISO , TFT_RST will then be connected to VCC. For the user button that is conflicting with TFT_CS i will chose another pin ,...

Hello Jean Marc :) I just have a question about pin-out when i want to use a SPI TFT LCD. As i see , the 2 user keys are in conflict with TFT_RST and TFT_CD , the I2S audio data pin is in conflict with TFT_DC. Some...
