A nominal 3.7v Li-ion battery can be up to 4.2v when freshly charged.
Even at 3.7, it is above the rated maximum for an SD card. The SD card
spec has a rated voltage range of 2.7 to 3.6v (SD2 cards ...

VCC 3.7V lion battery. I use 0.1uF capacitor on power stage. I try more capacitor in space assembly on circuit breadboard.

hi temtronic.

I have new version compiler. 5.109 version.

sd card pin to pin serial connect on the board. dont have resistor.

I am having trouble reading SD CARD with 64 MHZ clock frequency. Communication is not possible. It actually takes a long time to read the card. After reading the file inside the card (55 seconds), it ...

Hello again.
I got good results with 32 MHZ. But my 64MHZ clock frequency stays high. 48MHZ is my max clock frequency. We can run it internally as 8-16-32-64 with PLL. Can I run 48MHZ with internal o ...

Seriously, you need ro update your compiler. 5.007, was beta at best and
has huge numbers of problems
You need to set the clock in the delay statement to _match_ the clock
you are selecting.
If yo ...

How old is your compiler?.
The newest compilers correctly program the PLL. However older compilers
sometimes did not.
If you have an old compiler then leave the #use delay at 64MHz,
but put back ...

I noticed something. After using the #define SDCARD_SPI_HW command, it was reduced to 1 minute 34 seconds. So the PIC still works at 16MHZ. It can be 18F45K22 INT OSC 16MHZ. 16X4=64MHZ working with PL ...

First, change your #use delay, and get rid of the setup_oscillator.

#use delay(internal=64MHz)

//setup_oscillator(OSC_16MHZ|OSC_PLL_ON)

You are currently telling the compiler you are running ...

Hello,

I draw Bitmaps using PIC18F45K22, ST7735 1.8″ TFT and SD card.
I have a problem. I define TFT and SD CARD connections manually. I am not using hardware definition. SPI1 outputs for SDCCA ...
