Hi. Is there a compatibility list of mobile phones and NFC chips, like M24SR? I tried to connect to M24SR on my Samsung S6 - no luck! Same problem on latest Samsung and IPhone X. However, Blackberry PRIV recongizes it. May be, it is due to 14443-4 st...
Posted on February 08, 2017 at 16:54Currently CubeMX supports only FreeRTOS v.7.It is a really old version without power save features. This year FreeRTOS v.9 is already available. Are they going to support new FreeRTOS versions? Why they didn't sup...
Posted on April 19, 2016 at 11:33Bit-banding is a fine approach for manipulating bits, especially GPIO. In STM32L476 GPIO are located in AHB2 address space. However, AHB2 address space is located far beyond bit-band region: 0x40000000 APB1, APB2,...
Posted on April 14, 2015 at 15:14What is an AZB chip revision? It appears to be a package option. Micro explorer for example shows standard package and AZB package. I am not satisfied with how the port multiplexing was chosen, however it maintains c...
Thank you for your reply. You are right, the commercial antenna has low inductance, 0.9 uH. I erroneously implied that it has proper inductance value. However, in datasheet they have shown proper LC layout.https://media.digikey.com/pdf/Data%20Sheets/...
Thank you very much. After you answer I re-checked my workbench and found that it DOES CONNECT !! The problem was in long distance between antenna on my board and phone. https://www.st.com/en/evaluation-tools/b-l475e-iot01a.htmlIndeed, the board has ...
Posted on January 13, 2017 at 10:59Hi,I have the same problem. It seems having deeper roots..If I configure DMA Rx at channel 4 and do not use DMA Tx channel, transmission is OK.If I (manually or otherwise) set DMA2 channel 5 to Periperal 7 (DMA2->C...
Posted on April 19, 2016 at 14:15Great thanks! >> Bit-band is only for AHB1 & APBx. I see.. But it is not written explicitly somewhere, is it? BRR/BSRR is a good approach too. However, using bit-band (in other series) is faster as it doesn't requir...
