| S1D13700 driver code |
 Posted: Mon Nov 25, 2019 11:35 pm |

ccs c 5.091
processor dsPIC33EP512GM710
I'm looking for the s1d13700 driver code written to the ccs c compiler. Could you share it if you have it? The screen I use NHD-320240WG-BxTGH-VZ#-3VR
thank you very much

I looked. but it has never been more literally running.

What do you mean "it has never been more literally running".
You will have to change every 'int16' entry to 'unsigned int16', and every
'int8' to 'unsigned int8', and most of the pin references. Particularly the
byte wide output 'output_d', which you will have to either add a byte wide
output routine to do, or mask the port (the former is probably easier,
just declare a #BYTE variable to talk to the low 8bits of the port you want
to use, and connect the chip to this - set TRIS before using - same for the
read routine). Remember to use LAT for output and the port for input.
Fairly basic tweaking to make it work on the PIC33. |

I don't use port d. The pins I can use should be as follows. My hardware is suitable for these pins.
| Code: |
#define S1D13700_Data_A0 PIN_D5
#define S1D13700_Data_RW PIN_D13
#define S1D13700_Data_E PIN_D12
#define S1D13700_Data_CS PIN_D6
#define S1D13700_Data_RST PIN_C9
#define S1D13700_Data_DB0 PIN_F1
#define S1D13700_Data_DB1 PIN_G1
#define S1D13700_Data_DB2 PIN_G0
#define S1D13700_Data_DB3 PIN_F6
#define S1D13700_Data_DB4 PIN_F7
#define S1D13700_Data_DB5 PIN_G14
#define S1D13700_Data_DB6 PIN_G12
#define S1D13700_Data_DB7 PIN_G13

That makes it really hard. Splitting the output byte to bits on several
ports. You will have to do something like (in place of output_d):
| Code: |
void output_byte(uint8_t val) //assumes stdint.h is loaded
{
if (bit_test(val,0))
output_high(S1D13700_Data_DB0);
else
output_low(S1D13700_Data_DB0);
if (bit_test(val,1))
output_high(S1D13700_Data_DB1);
else
output_low(S1D13700_Data_DB1);
if (bit_test(val,2))
output_high(S1D13700_Data_DB2);
else
output_low(S1D13700_Data_DB2);
if (bit_test(val,3))
output_high(S1D13700_Data_DB3);
else
output_low(S1D13700_Data_DB3);
if (bit_test(val,4))
output_high(S1D13700_Data_DB4);
else
output_low(S1D13700_Data_DB4);
if (bit_test(val,5))
output_high(S1D13700_Data_DB5);
else
output_low(S1D13700_Data_DB5);
if (bit_test(val,6))
output_high(S1D13700_Data_DB6);
else
output_low(S1D13700_Data_DB6);
if (bit_test(val,7))
output_high(S1D13700_Data_DB7);
else
output_low(S1D13700_Data_DB7);
}
|
and a similar one reading the bits into a byte for input_d.
Though a bit cumbersome, this is as efficient in code terms as any other
solution. Lesson is though when laying out something that uses byte
wide data input/output, do try to put the pins onto consecutive port
bits. Will speed things and save a lot of code....

There's also a hardware solution, for maybe $2.
Buy a smaller PIC and code the diplay driver into it. Connect to your PIC on 1 I/O pin, then send display data to it.
There are 'interface modules' like this for the LCD1602 style LCDs, maybe someone makes them for the GLCD you have ? |

It only takes 0.8uSec to run the output_byte as shown. Fast enough I'd suspect
to be totally acceptable. So though not elegant. Good enough.
(assuming he is at 120MHz).
The chip itself is a GLCD to basic parallel interface, so probably not worth
trying to switch to using basic text mode.... |

Just written an 'input_byte' for the same configuration:
| Code: |
uint8_y input_byte(void) //assumes stdint.h is loaded
{
uint8_t rval=0;
if (input(S1D13700_Data_DB0))
bit_set(rval,0);
if (input(S1D13700_Data_DB1))
bit_set(rval,1);
if (input(S1D13700_Data_DB2))
bit_set(rval,2);
if (input(S1D13700_Data_DB3))
bit_set(rval,3);
if (input(S1D13700_Data_DB4))
bit_set(rval,4);
if (input(S1D13700_Data_DB5))
bit_set(rval,5);
if (input(S1D13700_Data_DB6))
bit_set(rval,6);
if (input(S1D13700_Data_DB7))
bit_set(rval,7);
return rval;
}
|
replace 'input_d' with a call to this. |

I offered the HW solution as it's 'old skool', had to make several over the decades to upgrade 'reliable' equipment .
hmm, sounds like a 'Flex-GLCD' driver might be an answer !

You were told by Ttelmah to do this:

You will have to change every 'int16' entry to 'unsigned int16', and every
'int8' to 'unsigned int8', and most of the pin references.

But you didn't do it. |

and..
there could be a timing probem.
delay_cycles(xx) is based upon the clock value.
if the original code was written where delay_cycle(1) = 1 us , that will be 5X faster( .2us), if your PIC clock is 5X faster than the original program.
there also might be the '5V PIC - 3V peripheral' problem, thoug I think that PIC is 3 Volts ? but what is the GLCD VDD ? |
