I'm looking at the Atmel AT89C5115 20-pin 8051-basedmicrocontroller as part of a project I'm contemplating. Theinstructions for the factory-default UART bootloader aren't entirelyclear on the subject. According to the application...
Hi,Just wanted to know if there is any way to use port P0 and P2 whileaccessing external memory, or do you have to go in for 8255s?I want to develop an application which has a really low number ofcomponents on the PCB.Thanks.
Hallo,ich möchte einen ganz einfachen Einplatinenrechner mit dem80C32 größeres,nur zum Taster abfragen undein paar LEDs ansteuern.Die Schaltungen,die ich beim googlenfand, waren mir zu "aufwändig" (Serielle Schnittstelle und AD-Wandler...
Hi All,Where it is preferable to store log/history parameters:in FLASH or in on-chip EEPROM ?I am using AT89C51ED2 8-bit MCU from Atmel.It has 2k EEPROM on-chip and 64kB Flash.EEPROM programming features:1) On-chip 2048 Bytes EEPROM.2)...
HiWe are developing a USB device which is based on AT91SAM7S64 which has a64K of flash in it. We want to store some specific data like Serial No ofthe device etc. into the flash of the microcontroller permanently. But theissue is we can not...
I=B4m trynig to develop a firmware for this two microcontrolers, butstill having not results.Already had read the datasheet, but it looks like not working anyway.If somebody have some tips, it would be very nice to tell us.Thanks.
