How to insert a delay between a characters text?
this not work...
printh 38 65 66 67 38
printh 38 68 69 70 38
printh 38 71 72 73 74 75 76 77 78 79 7A 38
Your ASCII characters need to be converted to their Hex values.
Your MCU will receive the byte, you need to cast the byte as a character.
Using the printh command means printh values in the HMI are fixed and static. They do not change.
There is no known method to send contents of string variables.
it works with delay, thank you !
sorry Patrick, I have another step:
how we can insert special char. <CR><LF> after a string?
print (example) 123456<CR><LF>
printh 0X0D 0X0D (hex for <CR><LF>) but result is 0x20 0x0d 0x21 0x92 not what I need.
