Discuss hardware and software design challenges, including NOR flash storage, OTA updates, component ID, and thermal management.
Posted on August 05, 2015 at 02:59Hi,I've been digging and researching how to keep the number of seconds in the system (i.e. system clock). On the STM32 it's quite easy as the clock counts into the 32bit (4x8) registers and you can load this with UT...
Posted on August 03, 2015 at 00:44What's your favorite C-Compiler for the STM8? What makes you prefer it over the others? What do you consider particularly important in a compiler? Philipp
Posted on August 02, 2015 at 23:15Please, help me to find the documentation and development tools (datasheet, user manual, programming manual, Assembler or C compiler, etc.) on ST90R30C6R microcontroller. I can't find nothing on ST.COM earlier then ...
Posted on August 02, 2015 at 18:11The STM8 has a bug inits division implementation relating to the use of the undocumented bit 6 of the condition code register (see ''Unexpected DIV/DIVW instruction result in ISR'' in various STM8 errata notes). ST ...
Posted on August 02, 2015 at 11:04The text claims that incw y writes x and thus Figure 12 shows a pipline stall at the following ld a, (x). But incw y does not write x, and in fact Figure 12 does not show a pipline stall. I suggest to fix this secti...
Posted on July 21, 2015 at 11:07Hello, I design DC-DC converter using eDisign and I make it with folowing parameters: Vin = 11-14 V Vout = 5 V Iout = 700 mA Design software limits maximal inductance for this IC to 10uH, but then IL ripples are quite...
Posted on July 27, 2015 at 10:00Hello, i'm trying to programm a M24LR-DISCOVERY board over the ST-Link V2 of a NUCLEO-F401RE board. As IDE i use ST Visual Develop with cosmic stm8 32k compiler. When i try to start the debugger i get the following er...
Posted on July 20, 2015 at 07:39In stm32f030 Usart not working if I change starting address from 0x08000000 to 0x08003000. I mean the Usart Interrupt is not happening. The Usart is in Half duplex mode. If I used starting address as 0x08000000 Usart ...
Posted on July 21, 2015 at 02:27I have a modified an example code from a STM8S300 to run on a STM8S105c6 Discovery, to output to a LCD. OK, it almost works, it compiles (using IAR workbench), it links, it loads into the STM8sDiscovery, but it hang...
Posted on July 16, 2015 at 17:05hi there!i´m using the Cosmic c compiler and STM8S microcontroller.i can´t find this information:how many machine cylces this function takes?for(conta=0;conta<10;conta++);it´s seem to me that the ''for'' takes 6 cycle...
