how do i convert 0x0f to 46 hex - Programming - Arduino Forum
2013年4月3日 · hey guys, little problem. i am working with rfid and i have two readers. the old reader gives me this for example: 0x30, 0x31, 0x30, 0x39, 0x36, 0x38, 0x32, 0x44, 0x43, 0x36. 10 bytes and on my lcd-display it gives me: 0109682DC6. the new reader gives me this instead: 0x01, 0x09, 0x68, 0x2D, 0xC6 which are only 5 bytes, but as you can see, it are the same …
microcontroller - PIC18F45J50 UART remappable problem
2015年7月7日 · Set Analog pins as digital... ADCON1=0X0F; Setting analog port pins to digital is done via the ANCONx registers, not ADCONx. To enable digital input on RP0 you must set bit PCFG0 in register ANCON0. BTW.. RP0 and RP1 represent pin 19 and 20 resp.. which is RB0 and RB1 normally.. Pins 19 and 20 on the PIC18F45J50 are RA0 (AN0) and RA1 (AN1).

2021年1月3日 · Hi, I am working on a 328p based system, and would like to protect the application code from reading (externally). I don't need the bootloader so I programed the 328p with an uno as an isp programmer. I would like to set the lock bits. I did some search for a week or so and found there are a lot information about fuses but little about the lock bits. From what I …
Port manipulation confusion - Programming - Arduino Forum
2020年8月9日 · I've got the following piece of code I'm trying to understand: inline void setAddress(int row, int col) { PORTB = row & 0x3f; PORTC = (PORTC & 0xf0) | ((row >> 6) & 0x0f); PORTB = col & 0x3f; PORTC = (PORTC & 0xf0) | ((col >> 6) & 0x0f); } I understand the basic of port manipulation, so in the above: PORTB = row & 0x3f; Row is AND with 0x3F and …

Understanding ISO-TP, Flow Control and Blocksize
2023年8月30日 · If the library you use handles that it might be cause problems or not. Also the ISO-15765 standard does not specifies any requirement when a sender fails to send a flow control and keep going on. In short 0x0F tells the sender side "SEND ME 15 CONSECUTİVE FRAME" and Sender sends the 15 consecutive frames and expects flow control again.
